2. HAZARD IDENTIFICATION & RISK ASSESSMENT (HIRA):-
HIRA is a process and documentation of identifying hazards, evaluation of risk and
applying suitable control measures to minimize the risk of harm by hazards at work place
Or
It is a systematic risk assessment tool that can be used to assess the risks of various
hazards.
Objectives of HIRA study:-
• Carryout a precise, basic examination of all potential risks implying staff, plant,
administrations and activity techniques.
• Identify the current shields accessible to control the dangers because of the perils.
• Suggest extra control measures to diminish the danger to worthy level.
• Prepare a Risk register that will help in ceaselessly checking these dangers, identify any
progressions and guarantee the controls are powerful.

3. Steps involved in Hazard
identification and risk
assessment :-
1. Planning
2. Hazard Identification
3. Risk assessment
4. Plan control
measures
5. Record keeping
6. Implementation and
review

4. Terms & Definitions used
 HAZARD:- A hazard is any source of potential damage, harm or adverse health
effect on something or someone.
 Consequence:- it is the degree of harm
 Likelihood:- likelihood is the probability that the consequence will occur
 Risk:- A risk is the likelihood of a substance, activity or process to cause harm.
Likelihood
Severity
Risk
Risk= Likelihood* Consequences

5. PLANNING
 Before starting on HIRA, the very first step is
to put together a risk assessment team to
conduct surveys and gather relevant
information.
 The community planning team gathers
information from members of the community,
provides feedback and helps guide the HIRA
via an advisory group.
 This makes it easier to ensure their safety
once a problem has been identified.

7. Risk Assessment
• It is a way of determining risks and danger in work place.
• Risk Assessment combines the consequences and likelihood of
all incident outcomes from all selected incidents to provide a
measure of risk.
A risk assessment is simply a careful
examination of
• What, in your work place,
• Could cause harm to people, so that
you can
• Assess whether you have taken
enough precautions or
• Should do more to prevent harm

10. Record Keeping
 Continuously track all danger evaluation reports (directly from stage 1) and update records
when new data is free. Documentation can likewise include: photos of awful wellbeing
rehearses, lab mishap locales, criticism from staff, and a record of the security clearances
acquired and security trainings went to by lab individuals..
 This record provides proof that the
assessment was carried out, and is
used as the basis for a later review of
working practices. You should be able
to read it. It should not be locked away
in a cupboard.

11. IMPLEMENTATIONAND REVIEW
 All new preventative measures
should be implemented only once
the risk assessment team obtains
approval from the principal
investigator or lab manager.
 Conduct a meeting a month or two
after implementing the new safety
measures to review their efficiency.
 get regular feedback from lab staff to
keep all safety measures relevant.
Hazards and risks may change over time so it is
important to review your HIRA regularly.

13. SAFE WORK METHOD STATEMENT
 A SWMS is a written document that sets out High risk construction work activities to be carried out at a workplace.
THE SWMS:
 Sets out the work activities in logical sequences.
 Identifies hazards.
 Describes control measures
 But this doesn’t imply that method statement are limited to jobs relating to constructions sector alone, it include
all industries wherein dangers are highly observed.
A SWMS is made to do these:
 Identify what kind of work or task is known as “high risk” or perhaps dangerous.
 Points out how the dangers and threat could affect an individual’s safety and health.
 Describing the way the danger control measure have to be carried out or even implement on the job.
 Assess and select control measure.
 Systematically plan the activity so that it can be completed effectively and efficiently.

14. HIGH RISK CONSTRUCTIONACTIVITIES
1. Involves person falling from more than 3m;
2. Involves demolition of an element of a structure that is load-bearing or otherwise related to the physical
integrity of the structure;
3. Involves the disturbances of asbestos;
4. Is carried out in or near a confined space;
5. Is carried out in or near a trench, tunnel, shaft, etc.;
6. Involves the use of explosives;
7. Carried out near pressurized gas distribution piping;
8. Carried out in area that may have flammable or contaminated atmosphere;
9. Involves diving work;
10. Carried out near energized electrical installations or services.

16. PREPERATION OF SWMS
What information must be included in a SWMS:
A SWMS must:
i. Identify the work that is high risk construction work.
ii. Specify hazards relating to the high risk construction
work and the risks to health and safety.
iii. Describe the measure to be implemented to control
the risks, and
iv. Describe how the control measures are to be
implemented, monitored and reviewed.
The SWMS should also identify the:
o date and location the HRCW is to be performed
o person/s responsible for ensuring selected risk controls
are installed and maintained
o names of workers consulted in the document’s
preparation.

17. PREPARE A SWMS
 Get together the pertinent specialists, their HSRs and directors; preferably at the area of proposed works.
 Audit the proposed works and think about any site explicit variables with potential to affect the works
 Guarantee all proposed HRCW exercises are recognized furthermore, dangers are recorded.
 Select the danger control gauges, and depict them close by every one of the dangers and dangers that are
recorded.
NOTE*-
 The content of a SWMS should provide clear direction on the control measures to be implemented.
 Avoid use of acronym.
 SWMS should not include the use of additional and extra use of added, spare, unnecessary, redundant unneeded,
and uncalled for words in addition to, and on top of what is necessary or essential.
 Remember who will be reading the SWMS.

19. How to complete the safe work method statement
5 Step guide for filling out a SWMS:-
 Talk with the applicable representatives, contractors and health safety representatives about what work will be high-
hazard, the assignments, and related hazards, dangers and controls.
 In the ‘key steps/ tasks involved’ column, list the work tasks in arranged order by how they will be completed.
 In the plant required segment, list the sort of gear or apparatus/plant needed to play
out a specific task.
 In the ‘possible hazard’ column, list the hazards and risk for each step or task.
 In the ‘safety controls and PPE’ column, complete the necessary control measures
needed for each step or task. These are to be examined by the relevant employees,
contractors and health safety representatives.

20. A HIGHRISKWORK SCENARIOTHAT WOULD REQUIRE A SAFE
WORK METHODSTATEMENT
 SCENARIO: Painting in a confined space.
 Painting inside a storage tank on an industrial site and could involve 2 or more painters with confined space work
training.
1. ELIMINATION
Do not undertake surface preparation or painting work in any confined space.
2. MODIFICATION
Use substances and systems of work that do not create hazardous environments.
Provide adequate ventilation and extraction to all potential confined spaces.
3. ADMINISTRATION
Identify all areas likely to be a confined space prior to commencing any work.
Develop a confined space entry permit for work in any confined spaces.
Consult the confined spaces register for the site to identify if any painting activities are likely to occur in any area likely to be
confined space.

21. CASE STUDY ON HIRA:
WATER TREATMENT PLANT

22. INTRODUCTION
 Water Treatment Plant (WTP) is an important infrastructure to
guarantee human and environment health
 As water supply, they have a key role in giving healthy clean water
access to the society.
 In the progress of this, environmental and health safety aspect becomes
things to be concerned about.
 The study was conducted using the HIRA (Hazard Identification and
Risk Assessment) method to identify potential hazards found in the
workplace.

23. LITERATURE REVIEW
 We must identify hazards and potential hazards in the workplace in order to be able to take action to
eliminate or control them.
 Rating the hazard is one way to help determine which hazard is the most serious and thus which hazard
to control first. Priority is usually established by taking into account the severity and Likelihood.
 The following factors play an important role:
Severity of exposure - impact when exposed to the hazard.
Likelihood - that an incident will occur when exposed to the hazard.
 Risk can be calculated using the following formula:
Risk (R) = Likelihood (L) x Severity (S).
 The results of risk assessment that presented in a risk matrix are essential to make decision on risk
control.

24. EXTREME RISK 15-25
HIGH RISK 8-12
MEDIUM RISK 4-6
LOW RISK 1-3
 Description of likelihood level
 RISK RATING
 Description of Severity level

25. RESULT
 Risk Assessment is performed using the Risk
Matrix as described in the literature study.
 The results obtained from this risk assessment
are the various potential hazards present in
the water purification process.
 According the existing categories of extreme
risk, high risk, medium risk and low risk then
the findings are grouped into each risk
category.
 Extreme categories that exist in the risk
assessment are chlorine leak and industrial
fires. 2

28. CONCLUSION
 WE HAVE NOTICED THE SIGNIFICANT
REDUCTION IN RISK LEVEL AFTER THE
ANALYSIS. BY HAZARD IDENTIFICATION
RISK ASSESSMENT WE HAVE REDUCED
THE RISK FROM HIGH LEVEL TO LOW AND
ACCEPTABLE LEVEL BY TAKING ALL THE
APPLICABLE SAFETY PRECAUTIONARY
MEASURES AND PREVENTIVE
MEASURES.
 ORGANIZATIONS WHETHER IT MAY BE
PROCESS/MANUFACTURING/CHEMICAL
PLANT CAN USE THE HAZARD
IDENTIFICATION RISK ASSESSMENT AS
AN EFFECTIVE TOOL AND PREVENT
THEMSELVES FROM CATASTROPHIC
CONSEQUENCES AND HAVE BETTER
PRODUCTIVITY, QUALITY WITH ZERO
